One of the rumors we haven’t heard about the iPad 2 is an OLED screen. That’s because there’s pretty much no chance, and it would be incredibly expensive and difficult to manufacture by the million. But that doesn’t mean Apple isn’t at least thinking about the power-economizing, great-looking display tech. These patents show that they’re working on implementing it, but not any time soon.
Patently Apple has a good summary of the patents, which are mostly technical (having to do with coatings, implementation of touch layers, and so on), so I won’t go into detail here. But I wouldn’t be surprised if the iPhone 5 goes OLED. The challenge is keeping that resolution, which is already at the edge of what’s possible with displays that size.
